WM0831

The WM0831 is designed as one kind of 8-bit analogue to digital converters (ADC) that can be used in (1)embedding with remote sensors; (2)equipment health monitoring; (3)automotive; (4)industrial control applications. This device has a differential input and two input multiplexer and with this input multiplexer, data is input to DI on the rising edges of the clock to setup the Mux and initiate conversion.

Features of the WM0831 are:(1)functionally equivalent to national semiconductor ADC0831 and ADC0832; (2)WM0831: differential or single ended input; (3)ratiometric reference input (fixed for WM0832); (4)serial I/O interface; (5)Input range 0 to Vcc with Vcc reference; (6)8 pin package, SO or DIP; (7)5V and 3.3V variants; (8)Total Unadjusted Error: +/-1 LSB; (9)8-bit resolution; (10)32 us conversion time at fclock = 250 kHz.

The absolute maximum ratings of the WM0831 can be summarized as:(1)Supply Voltage: 6.5 V;(2)Input voltage range Digital Inputs: GND - 0.3 V to VCC + 0.3 V;(3)Input voltage range Analogue inputs: GND - 0.3 V to VCC + 0.3 V;(4)Input current, any pin: ±5 mA;(5)Total Input current for package: ±20 mA;(6)Operating temperature range: TMIN to TMAX;(7)Storage Temperature: -65 to +150 ;(8)Lead Temperature 1.6 mm (1/16) from case for 10 seconds: D or P package: 260 .

The electrical characteristics of this WM0831 can be summarized as:(1)High level input current: 0.005 to 1 uA;(2)Low level input current: -0.005 to -1 uA;(3)High level output (source) current: -6.5 to -24 mA;(4)Low level output (sink) current: 8 to 26 mA;(5)Input capacitance: 5 pF;(6)Output capacitance: 5 pF;(7)Total unadjusted error: ±1 LSB;(8)Differential Linearity: 8 Bits.
